Answer 2

Given - Rate

Find - Time

Solution - In 2.5 years the simple interest will be 0.25 times the principal.

Simple interest = Principal*rate*time/100

Simple interest = 0.25*Principal

0.25*Principal = Principal*10*Time/100

0.25*100/10 = Time

Time = 2.5 years

So, in 2.5 years the simple interest will be 0.25 times the principal.
